Mastercure

What if its a old spartan they was killed? like they recovered the body and changed them to basically be a brainwashed cyborg spartan. I mean chief is AWOL. which i dont blame him..if i had to deal with del rios ass i would go rouge. but back to topic. Cheif is probably finding a way to stop the forerunners from returning and getting revenge on humanity for almost defeating them in war millions of years ago.
